• In July 2022, Mapp hurled a 15-kilogram pot plant at his 82-year-old mother’s head in her Tumbi Umbi home, inflicting fatal injuries
• After the killing, he pawned his mother’s TV and whipper snipper for $200 and used the cash to buy heroin before calling triple-0
• A jury convicted Mapp of murder in October 2024 after prosecutors rejected his offer to plead to manslaughter
• On May 29, 2025, Justice Ian Harrison imposed a 21-year sentence, backdated to Mapp’s July 2022 arrest, with a 15-year non-parole period
• The judge highlighted Mapp’s decades-long heroin addiction, fraught family history and spontaneous loss of control as central to his decision
